How can I stat up a troll in 5 different systems?I don't see how the underlying mechanics or scale are relevant to the stat block. If those mechanics end up with an attack roll of "+14 vs AC" in D&D 4E, "+12 vs AC" in Pathfinder, "+2 vs Physical defenses" in FATE, and "2d6 vs TN4" in Shadowrun, why can't those be on the same line in a stat block?
